8" Radius-sanding blocks

I Coated the fingerboard on my 2008 Fender fretless Jazz bass with slow drying epoxy. I tried to level the fingerboard with a regular flat block first. It worked, but it wasn't perfect by a long shot. I was ready to take my bass to my (excellent) luthier to finish the leveling job, when I read the reviews on the radius-ed blocks from StuMac. I'm really glad I decided to try it. I was able to do a much more professional leveling job with "the right tool". Now that I have a little experience with epoxy, and getting it leveled properly, I'll be able to do some of my other fretless basses, and also keep them re-coated, and/or touched up occasionally. I'm very pleased with the result. It seems like a lot of money for a piece of wood, but I promise you won't look back. I would definitely recommend these blocks to anyone pro, or amateur. The results are worth the price.
